Report: Pilot Gave Faulty Altitudes Before Crash

The Air Force B-1B bomber pilot who died with his wife had been reporting inaccurate altitudes minutes before his civilian plane crashed in Colorado Springs.

Transcripts from tower communications at the Colorado Springs Municipal Airport show air traffic controllers were concerned that Capt. Martin Anthony Riggan's altitude readings were incorrect.

An investigation by the National Transportation Safety Board found Riggan crashed about five minutes after he reported missing his approach to the runway. The NSTB said no engine problems were found. A final report on the crash's cause hasn't been issued.

Riggan and his wife, Nicole Riggan, died December 22 when their single-engine Mooney M20E went down in freezing fog. Riggan was stationed at Ellsworth Air Force Base near Rapid City.
